The true valueof premium solarSunPower customer guide
Not all solar is the sameFor over 25 years, SunPower has been deliveringhigh-efficiency premium solar solutions for homes.When you select SunPower panels you can be assuredthat you are getting the most powerful solar energypanels on the market1, panels that can dramaticallyreduce your electricity bill and can help you savemoney from day one of installation.greatly outweighs the initial cost.The expression ‘you get what you pay for’ rings verytrue in the solar industry, and with SunPower you aregetting the very best solar panels money can buy:the added benefits and value delivered by SunPowerAt SunPower we like to let the facts speak forthemselves, as you will see here as we outline theactual benefits and added value a SunPower premiumpanels deliver over their lifetime. Compared to an investment in Conventional Panels,an investment in SunPower can deliver a much greaterreturn for you and your family, as SunPower deliversmore energy, higher savings, greater reliability and astronger warranty.2ReliabilitySunPower Maxeon cells are designed and tested tothe highest possible standards to ensure reliabilityover the lifetime of the product. TMWhat makes SunPower Maxeoncells more reliable?The design of SunPower Maxeon solar cells is uniquebecause each cell is built on a solid copper foundation— providing the strength and durability neededto survive all weather conditions year after year.Conversely, Conventional Cells use a low-cost metalpaste on the front and back-sides to conduct thepower generated by the cell, and are thus vulnerableto failing when exposed to the elements.86% of Conventional Cells degrade throughcorrosion or cracking due to temperaturefluctuations. This causes them to steadily losepower over time or completely fail.3 SunPower sunique Maxeon cells are virtually impervious tothese issuesOnly27out of a million SunPower panelshave been returned under warranty41. SunPower has the highest efficiency panels, out of all 2600 panels listed in Photon International, Feb 2012.2. Definitions used throughout presentation: “Conventional Panel” is a 240W panel, 15% efficient, approx. 1.6 m2, made with Conventional Cells.“Conventional Cells” are silicon cells that have many thin metal lines on the front and 2 or 3 interconnect ribbons soldered along the front and back.3. Wohlgemuth, J. “Reliability of PV Systems.”Proceedings of SPIE, Aug, 2008.4. Out of 6.5 million panels built with Maxeon Gen 2 cells installed world-wide, Jan 2006 through June 2012

NTYAWARR25-year warranty: a differencethat mattersSunPower delivers an industry-leading 25-year combinedproduct and performance warranty1, guaranteeing9.1% more energy over 25 years. This means 25 years ofcomplete peace-of-mind for you and your family.Why is SunPower’s warranty better?What is the value of a warranty?When investing in solar it is important to understandwhat your product and performance warrantiescover and for how long.SunPower’s warranty guarantees both the product andits power output for 25 years. In the unlikely event thatyou have an u nder-performing panel, SunPower willwork with our Partners to repair or replace and install it.Product warranty Typically, a solar panel manufacturer’s warranty isfor 10 years. After that period you are not coveredshould a problem arise. The cost of replacing a singlepanel can be well over 1,500 when accounting forproduct, labour, testing and shipping costs.Performance warrantySunPower products are backed by a 25-year productwarranty, which covers panel removal, shipping and replacement, giving you complete peace-of-mind.100%Performance warrantyMany manufactures offer a 25-year “stepped”performance warranty, typically guaranteeing 90%performance output for the first 10 years then only80% for the remaining 15 years.9,1%95%MORE ENERGYSUNPOWER90%85%TRADITIONAL WARRANTY80%75%05101520YEARS25SunPower offers a 25-year linear performancewarranty that guarantees over 95% performanceoutput for the first 5 years, then a 0.4% degradationrate each year for the next 20 years.

Understanding the true valueof your solar investmentRetail ticket prices can often be confused with value,when the true value of a solar investment should alwaysbe calculated over its entire lifetime (25 years plus).Value can be calculated directly from different variablesthat make up a solar system, these include both inputsand outputs.INPUTSOUTPUTSSystem sizeNumber of panelsEnergy generated by the systemRoof area requiredThe value of that energyPanel efficiencySystem costOutlined below is a comparison between SunPowerpanels and some Conventional Panels. The associatedvariables are listed and the total value of the energygenerated is clearly highlighted.An investment in solar is a long term economicinvestment (25 years plus), it pays not to take shortcuts.It is important to ask questions before investing in a25-year plus asset, such as:— how efficient are the panels?— how is the product and performance warranty structured?— will the product manufacturer still be around in 10 or25 years?It is clear from the example that SunPower’s productis different, as it requires less panels and roof space togenerate more energy and value over its lifetime.The below example is based on current peak ( 0.29/kWh) and reportedfuture energy prices in NSW1.System Variables(All figures based over 25 years)SunPowerPremium PanelsConventionalPanelsSystem size (kWp)Number of panelsTotal roof area required (m2)Panel effciencykWh generated2Value of energy generated1SunPower energy advantage3.271016.320.1%137,002 73,94820.0%3.121320.815.0%114,932 61,644 0 1,500Warranty VariableReplacement cost of an underperforming panel after 10 years1.
